;; Oddly enough, there are two different implementations of
;; festival.el. One is distributed with the festival package
;; (http://festvox.org/festival), which provides the speech-to-text
;; executable. The other was written by Dave Pearson
;; (https://github.com/davep/festival.el).
;;
;; EmacsWiki points to Pearson’s version. And that is the version
;; which straight.el's loads by default. Neither version is provided
;; by either GNU ELPA, or MELPA.
;;
;; The version bundled with the binary package supplies
;; ‘festival-say-string’, Pearson's version supplies ‘festival-say’
;; instead. We support both, suppressing ‘check-declare’ warnings by
;; prefixing the filename with "ext:".
